Scanner A primer
Dealing with data in hard copy is usually difficult than data in soft format. Consider the disadvantage you would be in if you had to work somewhere without access to the modern world's wonderful information technology facilities. But with your portable scanner, you have your own work station wherever you need. You can convert all those troublesome documents into electronic format quickly and easily, and use your personal computer to do with them as you please. Without a portable scanner all the information in the world is ancient and more or less unusable.
